The first pinch-hit grand slam in major league history was hit on June 3, 1902 by Mike O’Neill of the Cardinals. The right-handed pitcher (yes, a pitcher!) hit the blast in the 9th inning off Beaneaters pitcher Togie Pittinger to propel the Redbirds to a 11-9 victory over Boston at South End Grounds.
